Completely mount the lower valve section (body,
seat, inlet nozzle). The pressure ring 124 is placed
on the sealing strip of the body.
See Fig. 21.
Fig. 21
Mount the complete upper section (without bellows
206, plug 204 and lifting aid 237) onto the valve
body.
Clean and grease the two threaded rods (approx.
150 mm) lining / 180° offset).
Tighten spring bonnet 513 with hex. nuts until they
sit tightly on the body 100. See Fig. 18.
The pressure spring 952/1 is now partially pre-
tensioned. The view into the outlet flange shows
the position of the spindle (distance between the
insert sleeve 308 and stem guide 306).
See Fig. 22
Fig. 22
This must be raised further until the distance
between the upper edge of the insert sleeve and
the edge of the stem guide is approx. 5 mm.
In order to raise the spindle 802 into this position,
the adjusting screw 538 is now pre-tensioned
approx. 25 mm (turned into the bonnet). Then
mount a distance sleeve approx. 35 mm long (or
hex. nuts with U-washer, see Fig. 17) onto the
now free spindle end.
Grease the end surfaces of the spacer sleeve well
so that these surfaces cannot "seize".
A hex. nut is screwed onto the spindle end and
countered with another hex. nut. See Fig. 17.
Undo adjusting screw 538 (turn out of the spring
bonnet 513) until the distance between the upper
edge of the insert sleeve and the edge of the stem
guide is approx. 5 mm. See Fig. 23.
When undoing the adjusting screw 538, hold the
spindle 802 with a wrench on the counter nut to
prevent it from turning so that the bellows 206 or
the spring-type pin 939/1 are not damaged.
Fig. 23
Undo the hex. nuts 920/1 (on the flange of the
spring bonnet 513) and lift off the entire upper
section.
Install pressure ring 124 in the thrust flange 117
(observe Section 9.6.5) and screw bellows 206
with plug 204 and lifting aid 237 onto the spindle
802. See Fig. 24.
Fig. 24
Assemble the entire upper section with the body
100. Tighten the hex. nuts 920/2 and hex. socket
screws 914/1 for the pressure ring 124.
